Latitude and Longitude

Understanding Latitude and Longitude

Lines of latitude and lines longitude cross one another.

They form a grid system around the earth.

Latitude Lines of latitude are

also called parallels. They circle the earth

parallel to the Equator.

They measure north and south of equator in degrees.

The Equator is at 0° latitude.

The North Pole is at 90°N (north).Maps101.com

Longitude Lines of longitude

are also called meridians.

They circle the earth from Pole to Pole.

They measure east and west of the starting line, at 0° longitude or the Prime Meridian. Maps101.com

Absolute Location Only one place can

be found at the point where lines cross one another.

Use degrees (°) and minutes (’) to give an exact spot where one line of latitude crosses one line of longitude – an absolute location.http://www.navfltsm.addr.com/

Hemispheres The equator circles the middle of the

Earth. It divides the earth into

hemispheres or “half-spheres.” North of the equator is the Northern

Hemisphere. South of the equator is the Southern

Hemisphere.

Hemispheres The Prime Meridian runs from north

to south. It divides the earth into half spheres

in the other direction. East of the Prime Meridian for 180

degrees is the Eastern Hemisphere.

West of the Prime Meridian for 180 degrees is the Western Hemisphere.

Using Latitude and Longitude

Use the information provided on your notes to answer the questions.

Review your answers1. On the blank next to each number of degrees on the

chart, place the letter E (east), W (west), N (north), or S (south).

2. Find “1” on the chart and write “equator” along this line. Draw a blue line over the equator.

3. The equator is 0 degrees latitude.

4. Latitude is measured b) north and south from the equator.

5. Latitude lines run a) east and west but measure distance b) north and south.

Review your answers6. Find “2” on the chart and write “Prime

Meridian” along the line. Draw a red line over the Prime Meridian.

7. The Prime Meridian is 0 degrees longitude.

8. Longitude is measured a) east and west from the Prime Meridian.

9. Longitude lines run b) north and south but measure distance a) east and west of the Prime Meridian.
